Air Flow Sensor
This 4" x 3-3/4" x 1-3/4" medical take-out air sensor has (3) ports coming off the main 3-1/8" x 3/4" ID chamber, (2) leading to one sensor and the other leading to a second one, then through circuitry on a mounted PC  board leading to a 10-pin output connector. Also has a PCB-mounted 3V coin cell battery. The sensors have input, output and trigger voltage and a voltage output, but we have no specs. Nice parts and pieces, though.
$14.50 EACH
Okay, they’re just strips of metal, but CJ says one of each and a grapefruit will get you at least a “C” at the science fair. The copper electrode is 100mm long x 18mm wide  x .8mm thick (3.94" x .7" x .041”). The zinc electrode is 4” long x 3/4” wide x .027” thick and stamped “ZN”. And both of them are awfully useful for crafters and jewelry makers, too.
